A pulmonary laceration can cause air to leak out of the lacerated lung [10] and into the pleural space, if the laceration goes through to it. [8] Pulmonary laceration invariably results in pneumothorax (due to torn airways ), hemothorax (due to torn blood vessels ), or a hemopneumothorax (with both blood and air in the chest cavity). [ 11 ]
These symptoms are very non-specific, and can be caused by other types of tumor in the lung or mediastinum more generally, and by other conditions. Imaging (X-ray, CT, MRI) may be used to determine the presence and precise location of a tumor, but not a specific diagnosis of PPB or other tumor. [ 3 ]
A lung cyst, or pulmonary cyst, encloses a small volume of air, and has a wall thickness of up to 4 mm. [3] A minimum wall thickness of 1 mm has been suggested, [3] but thin-walled pockets may be included in the definition as well. [4] Pulmonary cysts are not associated with either smoking or emphysema. [5]
Both chemotherapy (drugs to treat cancer) and radiofrequency ablation (destroying cancer with radio waves) can cause lung cancers to develop cavities, which is a sign of a good response to treatment. [2] It is possible to have both an infection and lung cancer in the same cavity; the most common combination is primary lung cancer and ...
A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness. [1] A bleb has a wall thickness of less than 1 mm. [2] By radiology definition, it is up to 1 cm in total size. [3]
This particular variant of lung cancer is usually asymptomatic and is found after chest x-rays are taken for other reasons. [7] Hemoptysis is seen occasionally [7] and, in some cases, distal obstruction of bronchi by blood clots or mucus plugs produces cough and/or infection. [1] Lesions often enlarge and progress slowly, over many years. [8]
The incidence of bronchiolo-alveolar carcinoma has been reported to vary from 4–24% of all lung cancer patients. [23] An analysis of Surveillance epidemiology and End results registry ( SEER) by Read et al. revealed that although the incidence of BAC has increased over the past two decade it still constitutes less than 4% of NSCLC in every ...
One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT scans. [ 4 ] The nodule most commonly represents a benign tumor such as a granuloma or hamartoma , but in around 20% of cases it represents a malignant cancer , [ 4 ] especially in older adults and smokers .
